Mathews and Iredale'’ s Manual of Australian Birds. 
[A Manual of the Birds of Australia. By Gregory M. Mathews and 
Tom Iredale, illustrated with coloured and monochrome plates by 
Lilian Medland. Vol. I. Orders Casuarii to Columbse. Pp. xxiv-f- 
279; 10 col. & 36 monochrome plates. London (Witherby), 1921.

Not content with his larger work on the birds of 
Australia, of which eight volumes are now complete, the 
indefatigable Mr. Mathews in collaboration with Mr. Iredale 
has now planned a new work on the same subject on a 
somewhat smaller and less ambitious scale, to be completed 
in four volumes, of which this is the first. 
As is now the case with the larger work, the species are 
treated of as a whole, and the subspecific races are only 
mentioned under the heading “ Distribution and Forms.” 
The other information in regard to breeding habits is con¬ 
cisely stated, and full description of the plumages are given. 
There are no keys, but the genera and families are fully 
diagnosed. The classification is somewhat novel and is 
somewhat on the lines of Sharpe’s c Hand-list,’ but the 
arrangement and names of the orders are altered; while 
in the present volume the Frigate-bird is raised to the 
dignity of a special order, and the Gulls, Shore-birds 
(Charadriiformes), and Tropic Birds are banded together 
under the order Lari. 
The monochrome plates of heads, bills, and feet will 
undoubtedly be found most useful to explain the generic 
diagnoses. Our only complaint is that they are not referred 
to in the text ; indeed, they would have proved more useful 
still if they could have been interpolated in the letterpress 
on the pages to which they refer. Seven subspecies have 
been named as new belonging to the genera Eudyptes, 
Heteroprion, Phcebetria, Sulita, Chlidonias (= Hydrochelidon 
auct.), and Pelecanopus.
